BOX OR CONTAINER OF SHEET MATERIAL.

Application filed March 23, 1922. Serial No. 545,967.

To aZZ whom it may concern:

Be it known that I, CoRNnLIUs AMBRUs'rEn, a citizen of the United States, residing at Roslyn, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Boxes or Containers of Sheet Material, of which the following is a specification. v

The object of the invention is to provide convenient means for emptying the box of its contents in small quantities at a time, for limiting the amount removed and for reclosing the box.

The invention will be claimed at the end hereof, but will be first described in connection with certain embodiments of it chosen from other embodiments for the sake of illustration in the accompanying drawings forming part hereof; and in which Fig. l is a perspective view of the box which could be made of cardboard; Fig. 2 is a developed view of the cut-out from which the box could be made.

Fig. 3 and Fig. t show another type of cardboard box and its cut-out respectively. Fig. 5 shows a box of telescope type which could be made of any sheet material. Fig. 6 shows another type of box in the open position, while Fig. 7 shows the same box closed as it would appear if made of cardboard; and Fig. 8 shows it when closed as it would appear if made of metal.

Fig. 1 shows a box such as is usually made from cardboard by cutting the necessary shape from a single sheet and then folding and securing the cut-out to form a box. Fig. 2 shows the cut-out from which this box can be made. y

In this case the end 1 is unsecured and is movable along the edge 2 as a hinge, the

flap 4 is a continuation of the end 1 bent at approximately right angles to it and introduced into the box between the edges of the bent over flaps, 3, 3, and the side 7 of the box. This flap 4: is the same length as the'side 7, so that when the end 1 is closed the side 7 is completely underlaid by the flap.

An extension piece 6 extends across the lower part of the side 7 inside the box and is fastened to the adjacent sides but is free from the side 7. The flap 4 then passes freely between the side- 7, and the extension 6, the latter acting as a guide to keep the flap 4 againstthe side 7 while allow ing these parts to move-freely along each other.

5 is an opening through the side 7 at the opposite end of the box from 1, the said opening being normally closed by the flap i. It is evident that by raising the end 1 of the box the flap 4 will be also raised so that the opening 5 will be uncovered, and the contents of the box allowed to escape, and further, that this escape can be regulated by the amount of opening disclosed and also terminated by again lowering the end and its attached flap, all without in any way disengaging the interlocked parts of the box. I

Fig. 3 shows a. similar box in which the opening 5 is at the same end of the box as the movable end, and in which, instead of the flap 4.- being withdrawn from behind the opening 5 in the side 7, there is a similar opening 8 in the flap 4. which coincides with the opening 5 when the end 1 is sufiiciently raised. In this case the box would be turned upside down to accomplish the egress of its contents.

This box is also provided with a guide piece 6 and in addition are shown 2 right angle cuts in the part of the flap extending past the guide piece 6. The results in the formation of two ears, 9, 9, which being bent slightly inwards, engage against the lower edge of the guide piece and prevent the flap 4: being withdrawn further than necessary to uncover the opening 5. At the same time these ears can be easily straightened to permit the flap to be inserted between the side of the box 7 and the guide piece 6 when the box is initially closed. Fig. 4c shows the cut-out corresponding to the box shown in Fig. 3.

Fig. 5 shows two box parts, each open at one end. of such relative size that the one part telescopes into the other. An open ing at one of the closed ends of one part. can then he closed or disclosed by moving one box part in or out of the other part. Such a box could be made of either cardboard or metal.

Fig. 6 shows a box with hinged end piece in which three flaps extend from the .end piece into the box and engage the three sides other than the one carrying the hinge. An opening 10 is shown in one of the flaps adjacent to the hinge. altho it could be located in the flap opposite the hinge if desired. When the end is closed the open ing is covered by the side of the box and is uncovered when the end and the attached flaps are raised, the other flaps however ensure the closure of the box at all other points. The flaps adjacent to the hinge being shaped at 11 to an arc of a circle about the hinge axis as a center, for a sufiicient distance, and being contained as a tangent to the are somewhat further as at 12, permit suflicient movement to disclose the opening 10 but prevent the complete disengagement of the end and attached flaps from the box.

Fig. 7 shows such a box, adapted to be made of cardboard, in closed position, the flap opposite the hinge being retained in position against the front of the box by a guide piece 13, similar to that shown and described in Figs. 1 and 3.

Fig. 8 shows such a. box adapted to be constructed of metal in which the edges 14 of the side and front flaps are rigidly attached and the hinged end and flaps together r'orm a rigid structure. The opening in Fig. 6 (also shown in Figures 7 and 8) has its upper edge noncoincident with the upper edge of the box immediately adjacent to the opening, consequently when the lid is closed the opening is completely sealed, since it is entirely covered by the overlying side. This same modification can be made with respect to the opening as shown in Figures 1 and 2 and It is evident that modifications other than those shown, but embodying the same principles, could be made. Without limiting myself to the specific designs shown in the drawings 1 claim as new and desire to protect by Letters Patent the following- 1. A box or container of sheet material, one end movable with relation to balance of box, a flap attached to and projecting from said end arranged to underlay and slide longitudinally upon a contiguous side of the box, an opening into the box so disposed as to be either opened or closed by the relative position of the movable end and its projecting flap, to the underlaid side of the box without the necessity of completely disengaging the sliding parts. i

2. A box or" sheet material, one end movable with relation to balance of box, a projecting longitudinally movable flap attached to said end and underlying one cbntiguous side of box, an opening in said side of box so disposed as to be covered by flap when moveable end is in one position, and uncovered when end is in other position, without the necessity of completely disengaging the moving parts.

3. A box of sheet material, one end moveable with relation to balance of box, a projecting longi ud nally movable flap attached to said end and underlying one contiguous side of box, a guide piece attached to box, permitting flap to slide between guide piece and side of box, but holding said flap in close relation to side, an opening in said side of box so disposed as to be covered by flap when moveable end is in one position and uncovered when end is in other position, Without the necessity of completely disengaging the sliding parts.

*IL. A box of sheet material, one end moveable with relation to balance of box, a projecting flap attached to said end and underlying one contiguous side of box, a guide piece attached to box, permitting the flap to slide between the guide piece and side of box, but holding said flap in close relation to side, an opening in said side of box and guide piece, so disposed as to be covered by flap when moveable end is in one position and uncovered when end is in other position, without the necessity of completely disengaging the sliding parts.

5. A box of sheet material, one end moveable with relation to balance of box, a projecting flap attached to said end and underlying one contiguous side of box, a guide piece attached to box, permitting flap to slide between guide piece and side of box, but holding said flap in close relation to side, openings in side of box and guide piece and sliding flap so disposed as to be obstructed when moveable end with projecting flap is in one position and to coincide when in other position without the necessity of completely disengaging the sliding parts.

6. A box of sheet material, one end moveable with relation to balance of box, a projecting flap attached to said end and underlying one contiguous side of box, an opening in said fiap so disposed as to be covered by side of box when end and flap are in one position and uncovered when in other position, without the necessity of completely disengaging the moving parts.

7. A box, a longitudinally sliding flap, opening or openings, so disposed as to be closed by the flap in one position and dis closed by the flap when in another position without the necessity of completely disengaging the fiap from the box.

8. A box of sheet material, a longitudinally sliding flap attached to moveable end of box, and projecting along side of said box, opening or openings into said box so disposed as to be obstructed in one position of flap and to be uncovered in other position, without the necessity of completely disengaging the sliding parts, stop parts on the flap and box so disposed as to engage to limit the motion of end of box and its attached flap, and prevent disengagement of the sliding parts.

9. A box or container, one end moveable with relation to balance of box, a flap projecting from said end arranged to underlie a contiguous side of box, an opening in the flap so disposed as to be either opened or closed by the relative position of the moveable end and its projecting flap to the edge of the underlaid side of the box, without the necessity of completely disengaging the moving parts.

10. A box or container, one end movable with relation to balance of box, attached flaps projecting "from said end arranged to underlie contiguous sides of the box and to close same in various positions of movable end, a side opening into the box with all edges non-coincident with the box edges of the surrounding side so disposed as to be either opened or closed by the relative position of the movable end with the attached flap to the edge of the underlaid side of the box, without the necessity of completely disengaging the movable parts.

11. A box or container, one end movable with relation to balance of box, attached flaps projecting from said end arranged to underlie contiguous sides of the box and to close same in various positions of movable end, a hole 1n a flap so disposed as to be 12.
